CHARLES J. BRBANK, OF ENID, OKLAHOMA,

RAILWAY-TRACK.

Specification of Letters Patent.

Patented April 13, 1909.

Application filed Apr14, 1908. Serial No. 425,235.

To all whom it may concern:

Be it known that I, CHARLES J. BURBANK, a citizen of the UnitedStatesresiding at Enid, in the county of Garfield and State of Oklahoma,have invented certain new and useful Improvements in Railway Tracks; andI do hereby declare the following to be a full, clear, and exactdescription of the invention7 such as will enable others skilled in theart to which it appertains to make and use the same.

My invention relates to railway tracks and particularly to tracksdesigned for the running of motor vehicles having the ordinaryconstruction of rubber tires.

The object of the invention is to provide a more economic constructionof roadway or track on which such vehicles may be run, the intentionbeing that motor cars shall be operated over this track to take theplace of street cars or inter urban service.

The invention consists primarily in constructing the rails as well asthe ties of concrete or other suitable composition instead of steel.

The invention also consists in the features of construction andcombinations of parts hereinafter described and specified in the claims.

In the accompanying drawing, illustrating the preferred embodiment of myinvention: Figure l is a plan view of a section of track constructed inaccordance with my invention. Figure 2 is a cross section thereof, andFig. 3 is a longitudinal section.

In carrying out my invention, I first prepare a foundation l of brokenstone about six inches in depth and extending below the rails 2. Saidrails are preferably made of mixed concrete composed of Portland cement,sand and crushed stone formed in molds or in any other suitable manner.The body of said rails are preferably reinforced with metal rods 3 andeach is provided with a flange 4 at its inner edge leaving a broad treadsurface 5 on which the wheels of the vehicles are adapted to run. Thefoundation of broken stone is built vup to the surface of the road ateach side of the rails as shown in Fig. 2. The treads of the rails arepreferably arranged substantially on a level with the roadway whiletheir flanges project upward therefrom. Cross ties or braces 6 are laidat the same time as the rails and are prefer ably made integraltherewith. The foundation of broken stone need not extend below thecross ties as the weight of the passing vehicles will come wholly uponthe rails. Said ties are also made of mixed concrete similar to thatused in making the rails and they are also reinforced with metal rods'7. The ties are preferably arranged in the hori- Zontal plane of therails, as shown. The ends of the reinforcing rods in the ties areextended into the bodies of the rails whereby said ties and rails areheld more securely together.

In order to anchor the track to the road bed, as may be desirable inmany cases, concrete posts 8 may be run down for a suitable distancefrom the track into said road bed. These posts or extensions are alsopreferably made integral with the rails and are located at properintervals as may be required by the formation of the ground over whichthe track is built.

It will be observed that while the construction of railway trackdescribed herein is much cheaper to lay than the ordinary steel rails,it satisfactorily fulfils all the requirements for the purpose for whichit is designed.

While I have illustrated and described herein the preferred embodimentof my invention, I do not limit myself as to details which may bechanged without departing from the spirit or sacrificing the advantagesof my invention.

I claim:

l. A railway track having composition rails and composition postsextending from said rails down into the road bed for the purposespecified.

2. A railway track having rails made of composition and laid upon afoundation, and composition posts extending from said rails through saidfoundation and into the road bed for the purpose specified.

3. A railway track comprising composition rails and composition tiesboth reinforced by inetal rods running longitudinally thereof.

et. A railway track comprising composie tion rails and composition ties7the latter being reinforced with metal rods running longitudinallythereof and having their ends extending into the bodies of said rails.

5. A railway track comprising composition rails having their treadsarranged substantially on a level with the roadway and flanges extendingupwardly from said treads, and composition ties arranged in thehorizontal planes of the treads of said rails whereby said ties do notproject above the roadway, said ties being reinforced withl metal rodsrunning longitudinally thereof and having their ends extending into thebodies of said rails.

6. A railway trackv comprising composition rails, composition ties, andcomposition posts extending from said rails down into the road bed forthe purpose specified certain of said posts being arranged at thejuncture of'said ties and rails.

71 A railway track comprising composition rails and composition tiesboth reina forced by metal rods, the reinforcing rods in said tieshaving their ends extending into the bodies of said rails, andcomposition posts extending from said rails down into the road bed forthe purpose specied.

In testimony whereof, I affix my signature, in presence of twowitnesses.
